You think Marmol would be more valuable to us as a closer than in his present role where he's probably more likely to come in with runners on in close games and such? I'd say it's pretty close, actually. Marmol isn't used exclusively in high-leverage situations, and presumably Gregg wouldn't be going exclusively to Marmol's role. If Gregg is going to be bad and the idea of Marmol taking only the one-run saves isn't going to happen, then yes, the Cubs are probably better off with Marmol closing.
